I hate that some of the best things in life are so fleeting.
Good TV shows like Arrested Development and Dog Bites Man (a severely under appreciated work of genius) get canceled too quickly because people are morons, the honeymoon period of a relationship passes too fast because women are ungrateful, a good cookie is done before you know it, orgasms are over in just a few seconds, and vacations... Vacations! Man, it feels like you just got to wherever you were going and you already have to pack to head back to the airport to leave. It sucks.
But my guess is, that's probably what makes all those things so good, huh. Sad that people need to have things disappear to be reminded of how awesome they are.
